Fast radio bursts (FRB) are millisecond luminous radio pulses with large dispersion measures (DMs), well in excess of the Milky Way contribution. There have been more than one hundred FRBs reported since [1]} found the first one from archival data. Among them, only thirteen FRBs have been localized [2]}, [3]}, [4]}, [5]}, [6]}, [7]}. Apparently, FRBs can be divided into to two types, repeating and non-repeating ones and their host galaxy properties may be different.
